Just launched ShopWiki, a search engine that crawls 120,000 stores to create its index of products.
Via AdRants: Shopwiki is using the anyone-can-edit Wiki format for the site's buying guides. In this manner, we suppose ShopWiki has jumped into the social media space. While it's not that different from a bunch of Amazon reviews, the Wiki is a single, ever changing document as opposed to a collection of individual comments/guides written by users and manufacturers.
